Application filed November 3, 1920. Serial No. 421,466. N

This ihvention relates to safety razors but more particularly to bladeholders for the same and has for itsprimary object to provide astructure'which is simple, durable 5 and efficient.

Another important object is to provide a form of blade holder which willpermit the use of a double edged blade in types of safety razor framesnow capable of using 1 only a single edgedblade.

Further objects of the invention are to save materials, to facilitatecleaning, and to provide a separable blade holder.

The many other objects and advantages 15 of the resent invention will bebetter understood Ey reference to the following specification inconnection with the accompanying drawings disclosing certain selected embodiments thereof in which:

Figs. 13 and 14' are res ectively front and end elevations of a modi edform of the invention. I v

Referring to the drawings the invention is shown to comprise a'baseplate 15 provided with inwardly turned portions 16 on opposite endsthereof forming a channel to receive the end edges of a blade 17. Thelower portion: of these end portions 16 are spaced sufiiciently from thebody of the base plate toermit the blade 17 to be slid upwardly terebetween to the desired position. The upper edge part 18 of each ofthese end portions is indented to press the present types of safetyrazors. In these razors the blade has usually been drop ed into place onthe guard and some means has been provided to press against the rearedge of the blade to force'the forward sharpened edge against the stopson the frame. In the form of safety razor illustrated in Figs. 2, 3 and4 the rear edge of the blade is engaged by the holder support comprisingthe spring pressed arm 21 on the frame 22 and pressed against thestops23 on this frame as the cover 24 was lowered into contact with theblade. With my holder this pressure would .be exerted a ainst the rearrojecting edge of the hol er, thus protecting the rear edge of theblade.

Sin 1e edge blades now in general use either ave a thickened rearedge'to provide the necessary rigidity or, in the case of the sheetsteel blade, a rigid head is pressed over the rear edge and erman'entlyat-' tached thereto. The thic ened blade *requires the use ofconsiderable steel and is.

expensive to produce so that the sheet metal blade has largelysuperseded it. When the single sharpened edge becomes dull, the

blade must be resharpened or the blade and,

head discarded as they are not separable.

-With the blade holder of the present invention the proper reinforcingis procured and the same holder may be used with an indefinite number ofblades of either the single or double edge type. I

The :holder may be free within the frame in the manner described but Ihave found it advantangeous to'igconn ect it to the frame permanentl';The,;=} form of {connecting means we (1 naturally vary with thenstruction of'the frame or might be vari in any particular type offrame. In the type of frame shown in Figs. 2, 3 and 4 the base 'plate 15of'the blade holder is provided '25 and are bent into ring form toprovide a hinge connection between the parts 15 and 27. A projection 28on the upper or rearward edge of the plate 27 is bent forwardly and theears 29 thereon folded about the spring pressed arm 21 on the frame 22to connect the holder to the frame when the cover 24 is raised bypressing on the outer extremity 30 thereof, the spring pressed arm 21swings rearwardly, causing the plate 27 to swing away from the base 31of the frame 22, and drawing the edge 20 of the blade 17 upwardl andaway from the guard teeth 32 and t e stops 23. This enables the lathercollecting between these teeth to be removed and the blade easilycleaned. The blade may now be removed from the holder and eitherreversedto utilize the reserve edge or a new blade inserted. The holder wouldremain permanently within the frame.

In Figs fi, 7 and 8 is shown a modified form of the invention comprisinga base plate 33 provided with inturned end por tions 34 to overlap theedges of the blade 35. The end edges of the blade are bevelled from thecenter and the end portions 34 are bent angularly to fit these bevellededges. This form is advantageous as the holderengages the blade only atits ends. The angularity of the end portions 34 prevents the bladeadvancing too far into the holder.

This holder may be used within a frame without attachment thereto in thesame manner as the previous embodiment but in order to illustrate theapplication. of my holders to another well known form of frame, I haveprovided the base late 33 with slots 36 to receive strips 37 0 metalwhich have their lower portions bent intoa loop 38 and their upperextremities folded about the spring arms 39 in the frame as shown inFig. 8. These spring arms 39 form the holder support which yieldinglypresses the blade against the usual stops 40 on the frame. Lifting ofthe cover 41 draws theblade away from the stops 40 and exposes the guardteeth 32 in the manner described in connection with the previousembodiment. In this construction also it will be noted that the pressureusually exerted against the rear edge of the blade is taken by theholder.

In Figs. 9, 10 and 11 is shown a modified form of holder practicallyidentical With the base plate of Fig. 1 except that a rigid head 42 isfitted over the upper edge portion of the base plate 43 and thedepending pfo jections 44 on the forward edge thereof are depressed tobind the u per part of the end portions 45 against the base plate and toretain the head on the holder. These depressions in the end portionsperform the stop action on the blade described in connection with theembodiment shown in Fig. 1 and prevents the rear edge 46 of the blade 47contacting with the lower edge 48 of the holder.

In Fig. 12 of the drawing is shown a modified form of holder in whichthe base plate 49 has its upper portion 50 folded forwardly over theremaining portion and sufliciently spaced therefrom to admit a blade 51therebetween. The folded corners 52 are indented to form a stop for theupper edge 53 of the blade to prevent contact of other than the extremecorners of the sharpened edge of the blade with the plate. The remainingportion of this sharpened edge is held away from the fold 53 of the baseplate by these stops. q

The channels 16, 34 and 45, as well as the folded over portion 50 ofFigure 12, con stitute a seat in which the blade is inserted edgewisefrom front to rear of the device,

and in each instance the insertion of the, blade is limited to positionits active edge projecting forwardly beyond the front edge of the holderand its rear edge short of the rear edge of the holder and protectedthereby.

Figs. 13 and 14 show a modified form of blade 54 which is slitted atboth ends and the edges of each slit bent outwardly in oppositedirections to engage with the bottom edge of a base plate to prevent theblade sliding upwardly too far between the retaining portions of theholder. 'Such slits and that this cutting unit is made up of a doubleedged razor blade and a holder therefor, these two parts of the cuttingunit beprovides a cutting unit for safety razors,

mg so associated that they may be placed as a unit in or upon differenttypes of safety razorflframes which are originally constructed for usingsingle edged blades only.

It will therefore be seen that my improved blade holder is simple inconstruction, durable and eflicient. It permits the use of double edgedblades in safety razors now only. capable of using a single edge blade.The holder is readily separable from "the blade so that one holder maybe used with an indefinite number of blades and'will' provide the properprotection and reinforcement. The holder makes possible a considerablesaving in materials because the base plate will strengthen the entireblade, and enable an exceedingly narrow blade to be used. This holder iscapable of useunattached to the safety razor or it -may be attachedthereto permanently. The

attaching of the holder to the frame greatly facilitates the cleaning.of the frame and the blade. The marking of the edges of a double edgeblade makes it possible for the user to continue to use one edge 'untilthis has become dull and then to use. the other edge. v
